Crack-A-JointÂ®Danley

Crack-A-Joint® by Danley® initiates a contraction joint in the slab when placed in wet concrete. Roll formed from a pre-galvanized strip eliminates the need for fill, as the steel edge acts as a support for the edge of the concrete. Crack-A-Joint is supplied in 3 m lengths in 25 and 45 mm heights.
